She looked thoughtful, then resigned; then she looked directly at him and smiled.
She got up to come over beside him and put her arms around him. "I'll be proud of you,"
she said. "And we'll have long, long lives after you get back." She ducked back as he reached to kiss her and said playfully, "None of that, you've got to get back. What are you going to do about Brad?"
"Well, I could go back to the motel--"
She said decisively, "Don't do it, Roger. Let him look out for himself. If he's up to something he shouldn't be, that's his problem. I want you to get back to the meeting, and--Oh, say, that's right! I'm going out again. I'll be passing quite near the motel. If I see Brad's car in the lot I'll put a note on it."
"That didn't even occur to me," he said admiringly.
"So don't worry. I don't want you thinking about Brad. With all that's coming up, we have to be thinking of you!"
Jonathan Freeling, M.D., F.A.C.S., A.A.S.M.
Jonny Freeling had been in aerospace medicine long enough to have lost the habit of dealing with cadavers. Particularly he was unused to cutting up the bodies of friends.
Astronauts didn't usually leave their bodies behind when they died, anyway. If they died in line of duty it was unlikely there would be any p.m.; the ones that were lost in space stayed there, the ones that died nearer home were usually boiled to gas in the flame of hydrogen and oxygen. In neither case was there anything to put on a table.
It was hard to realize that this object he was dissecting was Willy Hartnett. It wasn't as much like an autopsy as like, say, field-stripping a carbine. He had helped put these parts together--these platinum electrodes here, these microminiaturized chips in their black box there; now it was time to take them apart again. Except that there was blood. In spite of everything, Willy had died with a lot of wet, seeping human blood still in him.
"Freeze and section," he said, serving up a gobbet on a glass slide to his general-duty nurse, who accepted it with a nod. That was Clara Bly. Her pretty black face reflected sadness, although one could not tell, Freeling reflected, lifting out a dripping metal strand that was part of the vision circuits, how much of the sadness was over the death of the cyborg and how much over her interrupted going-away party. She was leaving to get married the next day; the recovery room just behind that door was still festooned with crepe and paper flowers for her party. They had asked Freeling if they should clear it away for the autopsy, but of course there was no need to; no one would be recovering in that recovery room.
He looked up at his surgical assistant, standing where the anesthesiologist would have been in a normal operation, and barked, "Any word from Brad?"
"He's in the building," she said.
_Then why doesn't he get his ass down here?_ is what Freeling thought, but he didn't say it, only nodded. At least he was back. Whatever grief was coming because of this, Freeling wouldn't have to carry it alone.
But the more he probed and fished, the more he found himself baffled. Where was the grief? What had killed Hartnett? The electronic components didn't seem to be wrong;
every time he removed one it was rushed off to the instrumentation people, who workbenched in on the spot. No problems. Nor did the gross physical structure of the brain give any immediate explanation . . .
Was it possible that the cyborg had died of nothing at all?
Freeling leaned back, conscious of sweat under the hot lights, instinctively waiting for his scrub nurse to wipe it off. She wasn't there, and he remembered and wiped his forehead on his sleeve. He went in again, carefully separating and removing the optical nerve system--what there was of it; the major sections had gone with the eyes themselves, replaced by electronics.
Then he saw it.
First blood seeping under the corpus callosum. Then, as he gently lifted and probed, the gray-white slippery sheath of an artery, with a bulge that had burst. Blown. A cardiovascular accident. A stroke.
Freeling left it there. The rest could be done later or not at all. Maybe it would be as well to leave what was left of Willy Hartnett as close to intact as it was. And it was time for the meeting.
The conference room doubled as the hospital library, which meant that when a meeting was going on, look-up research stopped. There were cushioned seats for fourteen people at the long table, and they were all filled, with the overflow on folding chairs, squeezed in where they could. Two seats were empty; they were for Brad and Jon Freeling, off on a last-minute run to the lab for final results on some slides, they said; actually so that Freeling could brief his boss on what had happened while he was "out to lunch."
Everybody else was there, Don Kayman and Vic Samuelson (now promoted to Roger's back-up man, and not looking as though he liked it), Telly Ramez, the chief shrink, all of the cardiovascular people muttering among themselves, the top brass from the administrative sectors--and the two stars. One of the stars was Roger Torraway, uneasily sitting near the head of the table and listening with a fixed smile to other people's conversations. The other was Jed Griffin, the President's main man for breaking logjams.
His title was only Chief Administrative Assistant to the President, but even the deputy director treated him like the Pope. "We can start any time, Mr. Griffin," urged the deputy director. Griffin's face spasmed a smile and he shook his head.
"Not until those other fellows get here," he said.
When Brad and Freeling arrived, all conversation stopped as though a plug had been pulled. "_Now_ we can begin," snapped Jed Griffin, and the worry to his tone was evident to everyone in the room, every person of whom shared it. We were worried too, of course. Griffin did not want to carry his worry alone and promptly shared it with everyone in the room: "You don't know," he said, "how close this whole project is to being terminated, not next year or next month, not phased out, not cut down. _Through_."
Roger Torraway took his eyes off Brad, and fixed them on Griffin.
"Through," repeated Griffin. "Washed out."
He seemed to take satisfaction in saying it, Torraway thought.
"And the only thing that saved it," said Griffin, "was these." He tapped the oval table with a folded wad of green-tinted computer printouts. "The American public wants the project to continue."
Torraway felt a clutching touch at his heart, and it was only in that moment that he realized how swift and urgent the feeling of hope that had preceded it had been. For a moment it had sounded like a reprieve.
The deputy director cleared his throat. "I had understood," he said, "that the polls showed a considerable, ah, apathy about what we were doing."
"Preliminary results, yes." Griffin nodded. "But when you add them all up and put them through the computer it comes out to a strong, nationwide support. It's real enough.
Significant to two sigmas, as I believe you people say. The people want an American to live on Mars.
"However," he added, "that was before this latest fiasco. God knows what that would do if it got out. The administration doesn't need a dead end, something to apologize for. It needs a success. I can't tell you how much depends on it."
The deputy director turned to Freeling. "Dr. Freeling?" he said.
Freeling stood up. "Willy Hartnett died of a stroke," he said. "The full p.m. report is being typed up, but that's what it comes to. There's no evidence of systemic deterioration; at his age and condition, I wouldn't have expected it. So it was trauma. Too much strain for the blood vessels in his brain to stand." He gazed at his fingertips reflectively. "What comes next is conjecture," he said, "but it's the best I can do. I'm going to ask for consultations from Ripplinger at the Yale Medical School and Anford--"
"The hell you are," snapped Griffin.
"I beg your pardon?" Freeling was caught off balance.
"No consultations. Not without full-scale security clearance first. This is urgent-top, Dr. Freeling."
"Oh. Well--then I'll have to take the responsibility myself. The cause of the trauma was too many inputs. He was overloaded. He couldn't handle it."
"I never heard of anything like that causing a stroke," Griffin complained.
"It takes a good deal of stress. But it happens. And here we're into new kinds of stress, Mr. Griffin. It's like--well, here's an analogy. If you had a child who was born with congenital cataracts, you would take him to a doctor, and the doctor would remove them.
Only you would have to do it before he reached the age of puberty--before he stopped growing, internally as well as externally, you see. If you don't do it by then, it's better if you leave him blind. Kids who have such cataracts removed after the age of thirteen or fourteen have, as a matter of historical record, an interesting phenomenon in common.
They commit suicide before they're twenty."
Torraway was trying to follow the conversation, but not quite succeeding. He was relieved when the deputy director intervened. "I don't think I see what that has to do with Will Hartnett, Jon."
"There, too, it is a matter of too many inputs. In the case of the kids after the cataract operation, what appears to happen is disorientation. They get new inputs that they have not grown a system to handle. If there is sight from birth onward, the visual cortex develops systems to handle, mediate and interpret it. If not, there are no developed systems, and it is too late to grow them.
"I think Willy's trouble was that we gave him inputs that he had no mechanism available to handle. It was too late for him to grow one. All the incoming data swamped him; the strain broke a blood vessel. And," he went on, "I think that will happen to Roger here, too, if we do the same thing with him."
Griffin turned a brief, assessing look at Roger Torraway. Torraway cleared his throat, but said nothing. There did not seem to be anything for him to say. Griffin said,
"What are you telling me, Freeling?"
The doctor shook his head. "Only what I've said. I tell you what's wrong, it's up to somebody else to tell you how to fix it. I don't think you _can_ fix it. I mean, not medically. You've got a brain--Willy's or Roger's. It has grown up as a radio receiver. Now you're putting TV pictures into it. It doesn't know how to deal with them."
All this time Brad had been scribbling, looking up from time to time with an expression of interest. He looked down again at his note pad, wrote something, regarded it thoughtfully, wrote again, while the attention of everyone in the room turned to him.
At last the deputy director said, "Brad? It sounds as though the ball's in your court."
Brad looked up and smiled. "That's what I'm working on," he said.
"Do you agree with Dr. Freeling?"
"No question about it. He's right. We can't feed raw inputs into a nervous system that hasn't got equipment to mediate and translate them. Those mechanisms don't exist in the brain, not in anybody's brain, unless we want to take a child at birth and rebuild him then so that the brain can develop what it needs."
"Are you proposing that we wait for a new generation of astronauts?" Griffin demanded.
"No. I'm proposing we build mediating circuits into Roger. Not just sensory inputs.
Filters, translators--ways of interpreting the inputs, the sight from different wavelengths of the spectrum, the kinesthetic sense from the new muscles--everything. Look," he said,
"let me go back a little bit. Do any of you know about McCulloch and Lettvin and the frog's eye?" He glanced around the room. "Sure, Jonny, you do, and one or two of the others. I'd better review a little of it. The frog's perceptual system--not just the eye, all of the vision parts of it--filters out what isn't important. If a bug passes in front of the frog's eye, the eye perceives it, the nerves transmit the information, the brain responds to it, and the frog eats the bug. If, say, a little leaf drops in front of the frog he doesn't eat it. He doesn't _decide_
